Definitions

  • the present invention relates generally to a mold for casting concrete test cubes. Conventionally, such cubes are formed for testing the compressive strength of cast concrete in special test laboratories.
  • the term "test cube” as used in the trade also encompasses other geometric configurations, the most common of which is a cylinder.
  • the term “test cube” is used herein in a similar non-restrictive manner.
  • An aspect of the present invention resides in providing a mold for so-called concrete test cubes, which is composed of a unitary vertically extending wall which defines a tubular enclosure having a first projection which extends angularly, i.e., sideways, from the enclosure, on the outside thereof, to provide an impact surface when the enclosure is tilted from a vertical to a substantially horizontal position.
  • the enclosure further includes at least two vertically extending projections arranged substantially diametrically opposite each other and formed on the top surface of the enclosure, and a bottom panel secured to the bottom of the enclosure and having an opening provided therein.
  • the panel and the enclosure are formed of plastic or plastic-like material.
  • FIG. 1 is a perspective view of the device in accordance with the present invention.
  • FIGS. 2 and 3 are views similar to FIG. 1, showing modifications of the invention illustrated in FIG. 1.
  • a mold of a one-piece, i.e., unitary, construction which is formed of a suitable synthetic material, such as plastic, and includes, see FIG. 1, sidewalls 1 projecting beyond a forward wall 2 and form at each terminal end a semi-circular tilting member. Parallel to the forward wall 2 there is arranged a rear wall 4, both of these walls are slightly higher than sidewalls 2.
  • the walls 1, 2 and 4 form an enclosure as shown in FIG. 1, with the bottom thereof being closed by a panel 5 provided with a valve or hose opening 6.
  • the mold of synthetic or plastic-like material established heat storage during the exothermic bonding or setting of the concrete, even when the mold with the test cube is submerged in water. This permits a complete bonding so that comparable, reproducible load factors can be measured on the test cube.
  • the heat storage increases the reaction speed and reduces the time required for bonding.
  • FIG. 2 there is shown a modification of the device shown in FIG. 1.
  • the walls 1,2,4 are surrounded, elevationally about midway, by a circumferentially extending continuous strip 3a and on the top edge of the four side walls panels (1,2 and 4), at the four corners of the mold, there are formed four spacer legs 7.
  • the concrete is leveled between the spacers 7 to provide a smooth surface which is flush with the top margin of the walls.
  • the mold shown in FIG. 3 is a modification of the device shown in FIG. 2.
  • wall forms a single, continuous circular structure.
  • the opening 6 may be covered by a plastic cap.
  • the mold is simply lifted, or kicked, so that the mold is tilted and falls sideways and comes to bear against the strip 3a, or projection 3, and then is tilted further until the mold is completely upside down with bottom panel 5 now being at the top.
  • the impact is usually sufficient to loosen the finished test cube with the smooth plastic mold, and the cube can move downward a little due to the positioning of the spacers 7, or the equivalent projections of panels 2 and 4.
  • a hose with air or water is now placed into the opening 6 which causes the cube to further separate from the mold.
  • loose concrete particles within the mold can be flushed out and the mold is immediately usuable again.
  • the rounded projections 3 facilitate the tilting of the mold in a rolling contact manner. While projections 3 require that the tilting be started by exerting forces against the rear wall 4, in the modification according to FIG. 2, these forces may be placed against any side panel (1,2,4). In either case, the two step approach is quite effective to separate the cast cube from the mold.
